Polytetrafluoroethylene (PTFE) is the main variety of fluoroplastics. At present, the three main products of PTFE seals are suspension resin, disperse resin and deep shrinkage dispersion, which account for 50%-60%, 20%-35% and 10%-20% of the consumption respectively. Suspension PTFE is mainly used for sealing rings, gaskets, chemical pumps, valves, pipe fitt...

Polytetrafluoroethylene (PTFE) has many excellent comprehensive properties and is widely used as corrosion resistant materials, sealing materials, medical materials, filtering materials, aviation materials, etc.1. Application of filter materialsAt present, PTFE fibers are mainly used to make high temperature and corrosion resistant filter materials for flue ...

Tetrafluoride compensator is also called expansion joint or expansion joint. The utility model is composed of a bellows (an elastic element) constituting the main body of the bellows and accessories such as an end pipe, a bracket, a flange, a conduit, etc. The utility model belongs to a compensation element. Tetrafluoride compensator uses the effective expan...

Tetrafluoro bellows are deformed by bellows to relieve the pressure from the transport medium in the pipeline, as well as the expansion of the pipeline caused by the heat generated in the transportation process, which will affect the service life of the tetrafluoro bellows. Because now bellows are widely used in various fields, the gas pipeline is widely use...

Tetrafluoride compensator is an important part of anti-corrosion pipeline, which plays an irreplaceable role in modern industry. It can be divided into steel lining, spraying type, medium-voltage mesh sleeve and other common types, below we will understand the nature of these types.1. Tetrafluoride compensator with steel lining is made of stainless steel and...

In most of the direct buried pipelines in China, after the installation of the direct buried pipeline, the shell of the tetrafluoro compensator and the corrugated layer form an integral whole. Under the working condition, the insulation layer and the insulation layer can not be expanded. Therefore, the groundwater can directly contact the working pipe and th...

The main advantage of stainless steel tetrafluoro bellows is durability, but there are still many illegal businesses using inferior raw materials to produce bellows, so it is crucial to know how to choose stainless steel bellows. So how to choose?In addition to working medium, working temperature and external environment, the material selection of stainless ...

Thread connection is mainly suitable for small diameter pipelines. When joining, it is usually necessary to wrap fluoroplastic sealing tape around the threaded joints, or coat with thick paint, wrap hemp wire and other sealing materials to prevent leakage. When the pressure is above 1.6 MPa, gaskets are usually added to the end face of the pipe. This connect...

Fatigue life design can be seen from the failure type and cause analysis of tetrafluoro compensator that the plane stability, circumferential stability and corrosion resistance of bellows are all related to their displacement, i.e. fatigue life. Low fatigue life will lead to the decline of the stability and corrosion resistance of bellows. According to the t...
